Di-Stearyl Amine
Water Treatment
Di-Stearyl Amine is a long-chain secondary amine composed of two stearyl (C18) groups bonded to a nitrogen atom, typically appearing as a white to light yellow waxy solid or soft paste with a mild fatty odor. It is practically insoluble in water but soluble in alcohols, hydrocarbons, and other organic solvents. Due to its strong hydrophobicity and ability to form stable surface films, Di-Stearyl Amine is used in water treatment as a corrosion inhibitor and antiscalant. It adsorbs onto metal surfaces, creating a protective, non-polar barrier that helps prevent oxidative and acid corrosion in systems such as cooling towers and closed-loop water circuits. It also assists in foam control and sludge conditioning in wastewater systems.
